Self or Bus Power: Selects between Self- and Bus-Powered operation.
0 = Bus-Powered operation. (BUS Default)
1 = Self-Powered operation. (SELF Default)
Note: If Dynamic Power Switching is enabled, this bit is ignored and the
SELF_PWR pin is used to determine if the hub is operating from self or bus
power.
Port Indicator Support: Indicates implementation of LED indicators
0 = No LED indicators.
1 = LED indicators.
High Speed Disable: Disables the capability to attach as either a High/Full-
speed device, and forces attachment as Full-speed only i.e. (no High-Speed
support).
0 = High-/Full-Speed. (Default)
1 = Full-Speed-Only (High-Speed disabled!)
Multi-TT enable: Enables one transaction translator per port operation.
0 = single TT for all ports.
1 = one TT per port (multiple TT’s supported)
